If you do not feel ashamed, then do whatever you like.
Narrated Abu Masud Uqba (may Allah be pleased with him):
The Prophet (may Allah’s peace be upon him) said:
“One of the sayings of the prophets which the people have got, is: ’If you do not feel ashamed, then do whatever you like.’”
[Sahih Al Bukhari; Bokk 56, # 690]
